Relativistic effects on the nonlinear propagation of electron plasma waves in dense quantum plasma with arbitrary temperature

–Relativistic effects on the linear and nonlinear properties of electron plasma waves are investigated using the one-dimensional quantum hydrodynamic (QHD) model for a two-component electron-ion dense quantum plasma with an arbitrary temperature and streaming motion. It is shown that the relativistic effects significantly affect the linear and nonlinear properties of electron plasma waves. Depending on the value of electron degeneracy parameter and the streaming velocity both compressive and rarefactive solitons can be excited in the model plasma under consideration. The importance of the result is also pointed out. Keywords––Quantum plasma, Quantum hydrodynamic model, finite temperature, solitary structure, relativistic effect
